MINE-CAR STOP.

Application filed. May 7, 1914.

To all whom it may concern Be it known that 1, JOHN T. PERO, a citizen of the United States, and a resident of Parsons, in the county of Luzerne and State of Pennsylvania, have invented a new and Improved Mine-Car Stop, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to pro vide means for arresting the downward progress of an elevator in a mine shaft, the operation of which serves to release, for delivery to the elevator, a waiting car; and to provide means for preventing the overrunning of cars into the shaft when the elevator is not in position to receive said cars.

In the drawings: Figure 1 is a longitudinal vertical section of a track bed and cars mounted thereon, showing in conjunction therewith a fragment of an elevator adapted to receive the car, said elevator being in operative position; Fig. 2 is a top plan view of the same, the bodies and frames of the cars being removed to show the running gear thereof; Fig. 3 is a detail view in perspective, of an apron employed to support the elevator; Fig. 4 is a detail View in perspective, showing a modified form.of the buffer mechanism for stopping the cars on their way to the elevator.

As seen in the accompanying drawings, a track-bed is arranged to deliver cars upon the rails of an elevator 9. The elevator 9 is arrested when descending, by an apron 10, so that the rails 11 on the platform of the elevator register with rails 12 on the track-bed of the mine lever. The section of track-bed immediately adjacent the elevator shaft is inclined, to deliver the cars 13 by gravity to the elevator 9, whenever free to do so. The cars are normally prevented from running into said shaft, by means of trip plungers 14 and 15, and buffer blocks 16 and 17 forming braces for the same. It will be understood, however, that the plunger 15 is not called into operation except when the plunger 1 is placed in its inoperative position. The plungers 1 1 and 15 are arranged in pairs, each membenof the pairs being operatively connected with the lifting arms 18 and 19, respectively. The arms 18 and 19 are rigidly mounted on rock- Specification of Letters Patent.

ing ts 0 and21, respectively, which shafts are provided with bearings in blocks 22 and 23 on stagings 24c and 25 disposed in a pit 26 provided under the track-bed adjacent the elevator shaft.

The shafts 20 and 21 are rocked when the shaft 27 is rocked. The shaft 27 is held normally in position by a weighted member 28 disposed on a lever 29, adjacent the end thereof. The levers 29 are rigidl connected with the shaft 27, and have forward extensions 30, as best seen in Fig. 1 of the drawings. The operating connections between the shafts 27, 20 and 21 consists primarily of short arms 31, which are fixedly mounted on the shaft 27, and the link bars 32 and 33 connecting said short arms 31 with short arms 31 and 35 mounted rigidly upon the shafts 20 and 21, respectively. Suitable pivotal connections between the short arms above enumerated and the link bars 32 and 33 are provided. It will be noted that the short arm 34 extends below its shaft 20, while the short arm 35 extends above its shaft 21. The result of this arrangement is that the shafts 20 and 21 are reversely rotated when moved by the link bars 32 and 33, and the plungers 141- and 15 are moved simultaneously in opposite directions. Hence, when the plungers 14 are lowered to the position shown in full lines in Fig. 1 of the drawings from the path of the axles 36 of the leading car 13, to release the same, the plungers 15 are lifted into the path of the next succeeding car, to arrest the same. The shaft 27 is rocked to the position shown in full lines in Fig. 1 of the drawings by the elevator 9, when the same is lowered upon, to be arrested by, the apron 10. The apron 10 is provided with a series of lugs 37, the ends of which are bent over to form guides for thrust bars 38. The lower ends of the thrust bars 38 are bent into position offset from the apron l0, and each is divided to form a slot 39, into which the ends of the extensions 30 of the levers 29 pass. The thust bars 38 are supported by the extensions 30 of the levers 29, as shown best by dotted lines in Fig. 1 of the drawings. In the inactive position of said thrust bars, the upper ends 40 project beyond the resting shoulders 41 of the apron 10. The elevators 9 are provided with a striking plate 42 to seat upon the shoulders 41. This plate depresses the thrust bars 38, and the ends of the extensions 30 engaged thereby, to rock the shaft 27, with the result that the leading car 13 is released from the engagement with the plungers 1a, and said car is permitted to move down the incline of the rails 12, on to the rails 11 of the elevator.

The operation of the mechanism by which the plungers 1-1 are released from engagement with the leading car 13, has been described, also the reverse operation of the plungers 15, whereby the second car is held while the first car is delivered to the elevator. When now, in the course of operation, the elevator is lifted, the weighted member 28 is permitted to lift the thrust bars 38 and to rock the shaft 27 and parts connected therewith to the original position. This operation results in lifting the plungers 14; into operative position in the path of the axle 36 of the waiting car 13. The car which has been engaged by the plungers 15 now moves forward, until arrested by the plungers 14:, where it is held until, in the course of operation, the elevator 9 again depresses the thrust bars 38.

The apron 10 is manually swung outward in the path of the elevator 9 by means of levers 13 and rods 4-1 connecting the lower end thereof with lugs 15 on the apron 10. It will be noted that the levers 43, as best seen in Fig. 2 of the drawings, are disposed at the side of the track-bed on which the cars are manipulated. The length of the connecting rods ist may vary to suit the conditions under which the cars are being operated. for delivery to the elevator 9.

By means of mechanism constructed and arranged as described, an operator standing beside the cars may at will set the apron 10 in position to arrest a descending elevator and secure the operation thereby of the mechanism for releasing the car 13 which has been disposed in position for delivery to said elevator.

In Fig. 4: of the drawings is a modified form of the mechanism, wherein a horizontally-swinging bumper beam d6 is employed to engage the end framing beam 47 of the car 13, instead of the plungers lt and 15, which engage the axles 36 of said car. The beams &6 are pivotally mounted by means of a pin 48, on a sill 49, which is suitably anchored at the side of the track-bed. The beam 46 is furnished with a short arm 50, to which a link bar 51 is pivotally connected. The link bar 51 is also pivotally connected with a standing lever arm 52 fixedly mounted on the shaft 27. 'When thus equipped, it will be seen that as the shaft 27 is rocked, the beam 16 is swung horizontally into and out of the path of the cars 13. The modified construction above described is employed in situations where it is desired to dispense with the construction of the pit 26, or where a more or less temporary installation of a stopping mechanism is found advantageous.
